# What free MCP servers does TigZig offer, and how do I use them?

TigZig offers several free MCP servers that an AI agent (Claude, ChatGPT or your own client) can add as connectors and call as tools:

- **Database Query** - read-only SQL over Postgres and DuckDB.

- **Yahoo Finance** - financials, prices and market data for any ticker.

- **Technical Analysis** - indicator plus chart-read technical reports.

- **QRep / FFN** - security and portfolio performance and risk reports.

- **Markdown to PDF** - render a report to a PDF URL.

Most are open source (see the repos linked from each service). The full catalog, with per-server cards and endpoints, is at [https://www.tigzig.com/apis](https://www.tigzig.com/apis). A machine-readable directory of the servers is at [https://www.tigzig.com/.well-known/mcp/servers.json](https://www.tigzig.com/.well-known/mcp/servers.json).
